Application filed July '17,

adapted to completely withdraw the exhaust gases from locomotives which locomotives may be stopped anywhere along the track in the engine stall within the roundhouse.

An object of my invention is "to provide a sinokejack construction wherein all of the exhaust gases and the like may be carried away without permitting the escape of any gases within the roundhouse;

Another object of the invention is to provide a smokejack having increased draft facilities for carrying away all exhaustgases from a locomotive irrespective of the position of the locomotive under the jack.

A further object of the invention is to improve smokejacks for successful, commercial use.

Generally speaking, I carry out the preferred embodiment of my invention by providing a smokej'ack having an elongated hood arranged over and along the track of the stall in the roundhouse whereby the exhaust gases from a locomotive may be received, and providing a plurality of ventilating outlets from the hood passing upwardly through the roof of the roundhouse.

Since the advent of large locomotives the use of the present type of smokejacks has been such as to make it impossible to withdraw all of the exhaust gases from the locomotive through the ventilating outlets of the jack. It has been the usual practice in roundhouse construction to place the jacks in such osition thatthe locomotive would have to e stopped with its stack immediately under the hood of the jack. Carelessness in stopping locomotives has resulted in a partial removal of the exhaust gases with the result that'a considerable portion of the gases is permitted to escape in the roundhouse, fouling the atmosphere therein. My invention overcomes the above recited V sition.

objection jack 1 The above recited and other objects of my invention will beapparent from theifollovv ing description and. drawings and lwillilbe particularly pointed" out in the appended claims.- i

In the accompanying drawings:

Figure l is aside elevational view of the to the present 1 form; of; smoke preferred embodiment ofmy inventiomand Figure 2 is a partial end elevation ofithe arrangement of Figure 1.

In the form in which I havechosen to l illustrate my invention I have shown'a partial part of the roof 5' of. a roundhou'se. Suitably secured'in the roof 5 is a plurality of depending boltsor stay rods 6; The

smokejack of my invention comprises an elongated hood 7 which is made long enough to extend some distance along a stall track and which has its ends 8 and '9 converging upwardly for the purpose of directingthe exhaust gases from the locomotive towards the ventilating outlets' Referring to Figure 2., it will be observed that the'width of the hood is only slightly greater'than the diameter of the Ventilating outlets." T-he hood is made'p'referably with itssides of strips .10 of wood properly fireproofed and with theend members 11 of castirono-r the like, the parts being suitably secured together to form the hood of the invention." At the upper portion of the hood designated at 12 I apply two diverging funnel-like members 13 and 14 which are in arrangement and shape as shown in the drawing. These members are made preferably of metal such as castiron. Mounted on top of the members 13 and 14 are the ventilating outlets A and 13, each outlet being identical with the other as to manner of construction and arrangement. The outlets comprise a plurality ofsections 15, cylindrical in form, the bottoms of which sections are provided with marginal flanges 16, having at diametrically opposite points apertured lugs 17 which register with apertured lugs 18 suitably secured to the next lower section. After bringingthe adjacent sections together, bolts 19 are passed through the registering openings in the lugs 17 and 18 and secured b means of nuts applied to the ends thereo This flanged construction provides a smoket-ight stack or outlet and one which may be readily made; shipped and assembledinpo- T he j'members 20, which top members 13 and 14 and communicate with the lower ends of lower section 15 of the outlets, are in shape and form made to correspond to the section next below and next above, that is, rectangular below and circular above. The supporting stay rods 6 aresecured by means of plates 21 fastened near the lower edges of-iftheghood and which plates have laterally extended apertured lugs 22 through which the lower e' nds'of the stay rods 6 pass. Nuts 23;;pbsition the hood on the rods. As an ad ditional meansl for supporting the smokejacksinfiposition from; the roof 5 of the roundhouse, other rods 24 depend from plates 25 :and extend through apertured lugs :26}- suita-bly secured to the members 13 and flixofthe jack. In like manner nut-s 27 cooperate-withthe ends of the rods 24.

Where the ventilating outlets A and B pass-through the roof 5 of the roundhouse, thereof-is formed with enlarged openings 28;.which are greater in diameter than the .outside diameter of the outlets, and around gi' hfi upper marginal portions of the openings 28 are converging collar members 29 which support on their upper surface ring plates 2b,;ghaving central openings 31 through which, the ventilators A and B pass and givhichfalthough; not specifically so shown are preferably greater in diameter than said ventilators, thus providingventilating openiiigsjaround pipes A and B. The sections 32 of; the ventilators, which are the sections massing-through the roof, are not provided vith the apertured lugs 18 as the case with the other sections. The bolt-s 33 passing t l i rougl the apertured lugsBt on the sec- .;tions z 5 of the ventilatingmembers pass 40 openmgs 111 the rings 25. Asa means for downwardly through suitably disposed preventing the admission of rain or the like through the ring plates 25 I mount a hood 30 ad]acen t the lower flange of the section 35 arranged to overlie the opening as shown.

As a means for preventing the admission lof rain or the like through the openings in the upper ends of the ventilating members A and B, and also to prevent excessive back 50 draft, I provide cover members 36 support ed in spaced relation to the tops of the ventilating membersA and B by bolts 37 passing through apertured lugs 38 suitably disposed near the upper end of sections 39 of the ventilating members.

'1 A smokejack of my invention may be installed in a roundhouse with a hood over and along thetrack stall so that a locomotive may be stopped with its stack anywhere underneath the hood whereupon the exhaust gases will be directed inwardly and upwardly 1 and B. I If f 7 should be stopped near the left hand end'of through .the ventilating members A or lnstance, the locomotive the hood as viewed in Figure 1, most of the gases would pass'up through ventilator A. The gases which could not pass through this ventilator would be withdrawn through ventilator B. By reason of the open construction of the interior of the hood no gases will escape under the edges of the hood and into the roundhouse. In like manner, it a locomotive be stopped with its stack near the right hand end of the hood, the greater portion of the gases would pass through ventilator B, with the balance passing through A. It will be noted that I have provided gutters 40, arranged along the lower side edges of the hood, for the purpose of catching any moisture which may descend along the ventilators and hood.

lVhile I have described more or less precisely the details of construction of my invention, I do not wish to be understood as limiting myself thereto as l contemplate changes in form and proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.

I claim:

"1. A smokejack including a plurality of stacks passing through the root ofa roundhouse, and an elongated hood arranged to extend some distance over a track and with said stacks communicating with the interior of said hood, said hood having an unobstructed interiorwhereby any smoke entering said hood may be withdrawn through said stacks, and means depending from the roof and engaging said hood for supporting said jack in position in the roundhouse.

2. A smokejack including a hood elongated whereby to adapt it to extend longitudinally over a roundhouse stall track and having an open interior throughout its length, a plurality of stack outlets on the upper side of said hood, and vent pipes connected with said outlets.

hood positioned'beneath and secured to the roof of a roundhouse and arranged to extend over a track, and a plurality of stacks communicating with the interior of said hood and extending through the roof at I spaced intervals from each other.

Signed at Chicago, Illinois, this 10th day of July, 1922.
